Question

ПОМОГИТЕ ПЛИЗКИ!1111!!!Подберите коэффициенты полные и сокращенные ионно-молекулярные уравнения следующих реакций:1)Ca(OH)2+HNO3→Ca(NO3)2+H2O2)AICI+KOH→AI(OH)3↓+KCI3)K2CO3+HCI→KCI+H2O+CO2↑4)MgSO4+K2PO4→Mg3(PO4)2↓+K2SO4

Answer 1

1)Ca(OH)2+2HNO3→Ca(NO3)2+2H2O
Ca+  +2OH-  +2H+  + 2NO3-  = Ca+  +2NO3-  +2H2O
OH-  + H= H2O
2)AICI3+3KOH→AI(OH)3↓+3KCI
Al 3+  + 3Cl-  + 2K+  +3OH- =Al(OH)3 + 3K+  +3Cl-
Al 3+  +3OH- =Al(OH)3
3)K2CO3+2HCI→2KCI+H2O+CO2↑
2K+ + CO3(2-) +2H+  + 2Cl- =2K+  +2Cl-  + H2O +CO2
CO3(2-) + 2H+ =H2O + CO2
4)3MgSO4+2K3PO4→Mg3(PO4)2↓+3K2SO4
3Mg 2+  +3SO4 2-  + 6K+  +2PO4 3- = Mg3(PO4)2 + 6K+  + 3SO4 2-
3Mg 2+  +2PO4 3- = Mg3(PO4)2

Answer 2

Coefficients for Ion-Molecular Equations

1) The balanced ion-molecular equation for the reaction between Ca(OH)2 and HNO3 is:

Ca(OH)2 + 2HNO3 → Ca(NO3)2 + 2H2O [[1]]

2) The balanced ion-molecular equation for the reaction between AlCl3 and KOH is:

AlCl3 + 3KOH → Al(OH)3↓ + 3KCl [[2]]

3) The balanced ion-molecular equation for the reaction between K2CO3 and HCl is:

K2CO3 + 2HCl → 2KCl + H2O + CO2↑ [[3]]

4) The balanced ion-molecular equation for the reaction between MgSO4 and K2PO4 is:

3MgSO4 + 2K2PO4 → Mg3(PO4)2↓ + 2K2SO4 [[4]]

Please note that the arrow (→) indicates the direction of the reaction, and the downward arrow (↓) indicates the formation of a precipitate.

These equations represent the balanced ion-molecular equations for the given reactions. The coefficients in front of each compound indicate the number of moles or formula units involved in the reaction.
